TL;DR: Clean porcelain dinnerware by hand with warm water, mild dish soap, and a soft sponge, then dry immediately to prevent water spots. Skip the dishwasher for delicate or gold-trimmed pieces, and store plates with felt protectors to avoid scratches and chipping.
Step 1: Prep and Sort Your Porcelain
Before washing, scrape off food residue with a silicone or plastic scraper. Never use a metal knife or steel wool, which can gouge the glaze. Separate highly decorated, gold-rimmed, or antique porcelain from everyday pieces. These delicate items should never go in the dishwasher, as harsh detergents and high heat can dull metallic trim and weaken the glaze over time. For everyday white porcelain, check the manufacturer’s stamp on the bottom — if it says “dishwasher safe,” you have more flexibility, but hand washing still extends its life.

Step 2: Hand Wash with Mild Soap
Fill a basin with warm — not hot — water and add a few drops of mild liquid dish soap. Hot water can cause thermal shock, especially if the porcelain is cold, leading to hairline cracks. Use a soft sponge or a dishcloth to wipe each piece gently. For stubborn stains like tea or coffee tannins, make a paste of baking soda and water, apply it with your finger, and let it sit for five minutes before rinsing. Avoid abrasive cleansers, bleach, and citrus-based products, which can etch the glaze.
Step 3: Rinse and Dry Immediately
Rinse each piece under warm running water to remove all soap residue. Do not let porcelain soak for long periods; prolonged moisture can seep into unglazed foot rings and cause discoloration or mold. Dry immediately with a soft, lint-free towel. Air drying can leave mineral spots, especially if you have hard water. For pieces with gold or platinum trim, pat dry rather than rub to avoid flaking the metallic decoration.
Step 4: Store and Maintain
Stack plates with felt protectors, paper coffee filters, or thin foam rounds between each piece. Avoid stacking cups more than two high, and never hang delicate teacups by their handles. Store in a dry cabinet away from direct sunlight, which can fade colored glazes. For long-term storage, wrap each piece in acid-free tissue paper. If you notice a small chip on an everyday piece, you can smooth it with fine sandpaper, but never use chipped porcelain for hot foods or liquids due to bacterial risk.
FAQ
Q: Can I put gold-rimmed porcelain in the microwave?
A: No. Metallic trim can spark, crack, or discolor in the microwave. Even “microwave-safe” porcelain without metal should be tested first with a cup of water.
Q: How do I remove brown scorch marks from the bottom of a porcelain casserole?
A: Make a paste of baking soda and water, apply it to the stain, and let it sit for 15 minutes. Gently scrub with a non-abrasive pad, then rinse and dry.
Q: Is it safe to use vintage porcelain dinnerware daily?
A: Only if it is labeled lead-free or tested with a home lead swab. Many pre-1970s porcelains contain lead in the glaze, which can leach into acidic foods.
